TECHNICAL FIELD

This document relates to methods and materials for inhibiting nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activity. For example, this document provides compounds (e.g., organic compounds) having the ability to inhibit NF-κB activity within cells, formulations containing one or more compounds having the ability to inhibit NF-κB activity within cells, methods for making one or more compounds having the ability to inhibit NF-κB activity within cells, methods for inhibiting NF-κB activity within cells, and methods for treating mammals (e.g., humans) having a condition responsive to inhibition of NF-κB activity.

BACKGROUND

The transcription factor NF-κB is a key regulator of both the innate and adaptive immune response to various pathogens. Activated by an array of stressors, NF-κB protein complexes initiate expression of a wide array of cytokines and other inflammatory mediators. Inappropriate or excessive activation of an NF-κB regulatory pathway can lead to excessive inflammation, which may be harmful to an individual and may lead to numerous disease states. Reducing excessive inflammation, acute or chronic, may be beneficial, for example, in a number of auto-immune conditions.

Extemporaneous injection solutions and suspensions can be prepared from sterile powders, granules, and tablets. The injection solutions can be in the form of, for example, a sterile injectable aqueous or oleaginous suspension. This suspension can be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. A sterile injectable preparation also can be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol.

EXAMPLES Methods

25 k THP1-NF-κB-LUC cells were dispensed into 384 well plate (per well). Cells were treated with compounds with various concentrations for 2 hours before addition of LPS (10 ng/mL) for 18 hours. Secreted luciferase activity were measured using quant-luc reagents (1 bag of luc reagent dilute to 40 mL, use 10 μL per well). Data were normalized to vehicle control and graphed. Compound IC₅₀ towards inhibiting NF-κB were determined through Prism. Similarly, 10 k human PBMCs cells were cultured in 384 well plate (per well). Cells were treated with compounds with various concentrations for 2 hours before addition of LPS (10 ng/mL) for 18 hours, and supernatants were collected and assayed for TNF ELISA. Compound IC₅₀ towards inhibiting TNF release were determined through Prism.

Activity: “+” >10 μM, “++” >1 μM and <10 μM, “+++” >0.1 μM and <1 μM, “++++”<0.1 μM.
